[Seagull-users] Strange times in Response time statistics

[paroxyzm <luk...@gm...>]

Hi!

I set up my client.xml  to measure response time to INVITE message like 
this:

<define entity="traffic-param" name="data-log-period" value="1"></define>
  <!--define entity="traffic-param" name="data-log-number" 
value="1000"></define-->
*  <define entity="traffic-param" name="data-log-file" 
value="../logs/setup-delay.csv"></define>*
  <define entity="traffic-param" name="data-log-rtdistrib" 
value="3000"></define>

And changed client.scenario.xml like that:

This scenario is supposed to measure time difference between those two 
messages and dump it to the setup-delay.csv file..


But it is quite strange to me that those times are so big..

Dump Periodic;
1;1;
7;1;
<some text ommited>
Dump Cumulative;
1;1;
3;4;
6;1;
7;5;

In this example I've connected two laptops with 100Mb eth link, and also 
used Wireshark to measure the same time difference.

However wireshark showed that  there  was quite constant time difference 
of  1.1ms.

Hence my question:
    Are those correct times?
Did someone had something like this??

Thanks in advance
